Flow past an asymmetrically confined cylinder of shear-thinning viscoelastic polymer solutions has been experimentally investigated. We show that the flow asymmetry induced by the asymmetric geometry is enhanced at Weissenberg numbers (Wi) above unity; that is, the flow in the nonpreferred pathway decreases significan…
Abstract Regolith-hosted rare earth element (REE) deposits are a critical resource, particularly for heavy REEs. Iron oxide minerals are one of the key REE carriers in these deposits, and elucidating the biogeochemical behaviors of carrier minerals and associated REEs is crucial for ore genesis and sustainable extract…
Abstract Quantum dots (QDs) provide bright optical, electrochemiluminescent, and electrochemical readouts for molecular sensing and bioimaging, but by themselves they do not provide selectivity, matrix tolerance, or a reliable mechanistic assignment. Supramolecular macrocycles can address these limitations by adding c…
Hydrofluoroolefin refrigerant cis-1,1,1,4,4,4-hexafluoro-2-butene (R1336mzz(Z)) has attracted widespread attention used in heat pump (HP) and organic Rankine cycle (ORC) due to its environmental friendliness and excellent thermodynamic properties. R1336mzz(Z) inevitably contacts with lubricating oil during compressor…
Abstract The effect of x = Ce/(Hf+Ce) (0.15-0.25) on dielectric, ferroelectric, and piezoelectric properties was investigated together with the crystal structure for 500 nm-thick xCeO2-(1-x) HfO2 films. The films were deposited on (111) (indium tin oxide, ITO)//(111) (yttrium-stabilized zirconia, YSZ) substrates using…
The catalytic valorization of biomass-derived 5-hydroxymethylfurfural (HMF) provides an important route toward sustainable chemical production. Herein, we report a bimetallic Pt1Au1 catalyst supported on Vulcan XC-72R carbon (Pt1Au1/XC) that enables efficient aerobic oxidation of HMF to FDCA using NaHCO3 as a weak bas…
This chapter describes the development of a top-loading sample probe for neutron scattering experiments operating in a cryogen-free He-3 cryostat with high-voltage capability. The probe supports DC biases up to 10 kV while maintaining stable operation at temperatures as low as 400 mK. Parasitic heat loads are minimize…

Selective laser flash sintering (SLFS) is emerging as a promising route for binder-free additive manufacturing of ceramics. Monitoring local temperatures during SLFS allows correlations between processing variables and the temperatures required for SLFS. This study demonstrates a visible-near infrared (vis-NIR) imagin…
Abstract Super duplex stainless steels (SDSSs) are well known for their good mechanical properties and corrosion resistance inherited from the dual-phase microstructure with equivalent proportion of ferrite and austenite. The development of additive manufacturing has given rise to the use of more diversified material…
Abstract Polymer-based dielectric composites are pivotal for advanced pulsed power and power electronics, yet synergistically enhancing dielectric constant and breakdown strength remains a formidable challenge. Herein, we report a controllable layer-by-layer spray assembly strategy to fabricate ordered multilayer poly…
Python code and supporting files used to evaluate the explicit special-function formulas and generate the numerical illustration in the manuscript “Explicit Cartesian coordinates for three-dimensional clothoids”. The Cartesian coordinates are evaluated directly from the closed formulas; no numerical integration of the…
Abstract Protein-based recovery, detection, and separation of rare earth elements (REs) have accelerated since the discovery of the lanmodulin (LanM) proteins. While exceptional at total RE recovery, prior proteins, like most ligands, exhibited limited ability to differentiate REs, whether in detection or separations.…
Abstract 19F nuclear magnetic resonance (NMR) spectroscopy is widely used for structural elucidation of fluorinated molecules, but reliable prediction of 19F chemical shifts remains challenging because quantum-chemical calculations are computationally demanding and their accuracy can vary across diverse molecular envi…
Accurately predicting the acoustic properties of noise-reduction materials in real-world, flow-exposed environments remains a significant challenge in engineering. Classical models of microslit panels are unsuited for grazing flow conditions due to complex, nonlinear flow-acoustic interactions. To overcome this challe…

Environmental context Microplastics are widespread aquatic contaminants that can alter the environmental behavior of co-occurring pollutants. This study shows that polystyrene microplastics substantially modify silver nanoparticle bioaccumulation in Daphnia magna, increasing waterborne uptake, accelerating elimination…
This paper studies a deliberately closed testbed for scientific relation discovery. Classical mechanics is encoded as a typed graph with 159 quantity nodes, 131 equation nodes, and 15 law nodes, and an operator-conditioned graph attention network is trained to infer hidden quantities from partial observations. The tra…
Abstract Surface texturing can significantly enhance the tribological performance of materials. In this study, a novel moon-shaped surface texture was designed and optimized via computational fluid dynamics (CFD) simulations. The optimal geometric parameters were identified as R 1 = 100 μm, R 2 / R 1 = 1.5, and the co…
